What is an arrangement of minerals in flat or wavy parallel bands?
This arrangement is known as foliation, commonly seen in metamorphic rocks where minerals align in layers due to pressure and temperature changes during their formation.
Why do bands of minerals develop in most metamorphic rocks?
It's because of foliation. Foliation is defined as the arrangement of a set of minerals in parallel, sheet-like layers that lie perpendicular to the flattened plane of a rock.
What is the parallel alignment of minerals that have been stressed?
The parallel alignment of minerals due to stress is called foliation. Foliation results from the deformation of minerals under pressure, causing them to align in the same direction. This alignment gives the rock a layered or banded appearance.
Difference between schistose foliation and gneiss-to foliation?
A schistose foliation would be found in a metamorphic rock with a large amount of micaceous minerals, creating a flaky texturing with easily cleavable layers. Gneiss is more coarse in texture, not as easily cleavable along planes, and contains less micaceous minerals.
What is metamorphic foliation?
Metamorphic foliation is a preferred orientation of mineral grains within a metamorphic rock caused by pressure during metamorphism. This alignment creates a parallel arrangement of minerals, giving the rock a layered or banded appearance. Foliation helps geologists understand the history and deformation conditions of rocks during metamorphism.

What is the parallel arrangement of certain mineral grains that gives the rock a striped appearance?
The parallel arrangement of mineral grains in a rock that gives it a striped appearance is called foliation. This typically occurs in metamorphic rocks due to the alignment of minerals under pressure and heat, resulting in distinct bands or stripes. Foliation can provide clues about the rock's history and the direction of metamorphic forces.
How is foliation related to stress?
Foliation in rocks is a planar arrangement of mineral grains or structural features resulting from deformation under stress. The direction of foliation aligns with the direction of maximum stress, as the stress causes minerals to align and elongate perpendicular to the applied force. Therefore, foliation serves as a record of the deformation history and stress conditions experienced by the rock.
What is salty foliation?
Slaty foliation, is a type of parallel foliation consisting of fine-grained platy minerals. The direction of foliation is usually perpendicular to the direction of maximum stress.
